Important information about your Toyota
Occupant restraint systems
Toyota encourages you and your family to take the time to
read Section 1−3 of this Owner’s Manual carefully. In
terms of helping you understand how you can receive the
maximum benefit of the occupant restraint systems this
vehicle provides, Section 1 −3 of this Owner ’s Manual is
the most important Section for you and your family to
read.
Section 1 −3 describes the function and operation concern-
ing seats, seat belts, SRS airbags and child restraint sys-
tems of this vehicle and some potential hazards you
should be aware of. These systems work together along
with the overall structure of this vehicle in order to provide
occupant restraint in the event of a crash. The effect of
each system is enhanced when it is used properly and
together with other systems. No single occupant restraint
system can, by itself, provide you or your family with the
equal level of restraint which these systems can provide
when used together. That is why it is important for you and
your family to understand the purpose and proper use of
each of these systems and how they relate to each other.
The purpose of all occupant restraint systems is to help
reduce the possibility of death or serious injury in the
event of a collision. None of these systems, either individ-
ually or together, can ensure that there is no injury in the
event of collision. However, the more you know about
these systems and how to use them properly, the greater
your chances become of surviving an accident without
death or serious injury.
Seat belts provide the primary restraint to all occupants of
the vehicle, and every occupant of the vehicle should wear
seat belts properly at all times. Children should always be
secured in child restraint systems that are appropriate for
their age and size. SRS (Supplemental Restraint System)
airbags are, as their names imply, designed to work with,
and be supplemental to, seat belts and are not substitutes
for them. SRS airbags can be very effective in reducing
the risk of head and chest injuries by preventing contact of
the head and chest with interior portions of the vehicle.

The remote keyless entry system is
designed to lock or unlock all the
doors or activate the “PANIC” mode
from a distance within approximately 1
m (3 ft.) of the vehicle.
LOCKING AND UNLOCKING THE
DOORS
To lock and unlock all the doors, push
the switches of the transmitter slowly
and securely.
To lock: Push the “LOCK” switch. All the
doors are locked simultaneously. At this
time one beep will be heard, and the tail
lights and front side marker lights will
flash once.
Check to see that the doors are securely
locked.
If any door is not securely closed, locking
cannot be performed by the “LOCK”
switch and a beep will sound continuously
for 5 seconds. However, if the key is in
the ignition, a beep will not sound.
To stop the beep, close all the doors se-
curely or push the “UNLOCK” switch.To unlock: Push the “UNLOCK” switch
once to unlock the driver ’s door alone.
Pushing the switch twice within 3 seconds
unlocks all the doors simultaneously. Each
time the “UNLOCK” switch is pushed, two
beeps will be heard, and the tail lights
and front side marker lights will flash
twice.
When the “UNLOCK” switch is pressed,
the interior light and ignition switch light
come on. The lights remain on for about
30 seconds unless any door is opened
and closed.
You have 30 seconds to open a door after
using the wireless remote unlock feature.
If a door is not opened by then, all the
doors will be automatically locked again
and one beep will be heard, and the tail
lights and front side marker lights will
flash once.
If the “LOCK” or “UNLOCK” switch is kept
pressed in, the locking or unlocking opera-
tion is not repeated. Release the switch
and then push again.
“PANIC” SWITCH
Pushing the “PANIC” switch blows the
horn intermittently, flashes the head-
lights and tail lights, and turns on the
interior light.
The “PANIC” switch is used to deter ve-
hicle theft when you witness anyone at-
tempting to break into or damage your
vehicle.
The alarm will last for one minute. To stop
alarm midway, push the “PANIC” switch
once again, lock or unlock any door with
the key or transmitter, or turn the ignition
key from the “LOCK” to “ON” position.
The “PANIC” mode does not work when
the ignition key is in the ignition switch.
